R – How to prevent starting TaskManager in the Desktop

desktoptaskmanagerwinapiwindows

I am creating a new Desktop in Windows XP/Vista and 7 using win32 API.
This is more like having a secure Desktop and I don't want let any other application to be executed in that Desktop.

Well, in Windows XP if I press strg+shift+Esc or strg+alt+ent, in the Desktop which I created, I don't see the task manger on my Desktop but instead on the Default Desktop.

Well, that's ok, but in Windows Vista, doing the same I get the task manager in my Desktop where the user can start another application using File->New task (Run…) menu.

Here is my question, what is the best way to prevent task manager to be displayed in the desktop which I created or even prevent starting it?

1) using the registry key,
2) capturing the key strokes?
3) what else???

Thanks in advance!
